, 'To all whom it may concern:

relation to. the tanks and track,

Be it known that I, Hans CHARLES BEHR, a citizen of the United 'States, and resident ofJohannesburg, Transvaal, have invented certain new and useful Improvements in Means for Handling and Distributing Dewatered Crushed-Ore Products, 6110., of which the following is a specification.

This invention has reference to means for dewatering or separating water, solvent solution, or other liquid from crushed ore products or other granular or pulverulent material and for delivering the dewatered product into tanks, vats, pits or the like, for treatment by cyanide or other solvent solutions, water washes, or other liquids.

The object of the invention is to provide a transportable dewatering apparatus or device adapted to be placed in position above any one of a .plurality of treatment tanks or the like, for dewatering the crushed ore -product or the like, and delivering the dewatered product thereinto.

In accordance with my invention I provide a carriage or wheeled bridge or frame for carrying the dewatering apparatus or device, which carriage is adapted to traverse a track or rails suitably supported over the treatment tanks or the like. The mill pulp, crushed ore products or mixture of granular or pulverulent material and liquid, may be conveniently conducted by a pipe or launder arranged in a suitable position in and provided with outlets fitted with valves, gates or their equivalent at the different positions into which the dewatering apparatus is placed for discharging the dewatered mate- .sents it in plan.

rial into the several treatmenttanks. The water or other liquid separated from the crushed ore products etc. may be conveniently conducted away from the dewatering apparatus by means of a launder or pipe suitably arranged in relation to the several treatment tanks and track.

The invention will now be more fully described by aid of the accompanying drawings wherein:

Figure 1 illustrates one form of my invention in elevation, and Fig. 2 repre- Fig. 3 depicts a modified form of the'invention,adapted to a circular disposition of the treatment tanks or the like, and Fig. 4 represents it in plan.

Specification of Letters Patent. Application filed January 27, 1908.

Fig. 5 is a sectional elevation of a dewatering apparatus. Referring more particularly to the arrangement illustrated in Figs. 1 and 2, the several treatment tanks represented at 1, are shown arranged in two parallel rows;

consist of any desired numher. For each row of tanks 1 I provide an overhead track or rails 2, the inner or contiguous rails of which are carried b Y trestles or supports 3 and the outer rails by conveniently disposed trestles or supports 4. For each track a carriage or wheeled bridge or frame 5 is provided, which carriages are adapted to traverse from end to end of their respective tracks 2 in order that they may be placed centrally or otherwise as preferred over any one of their series of tanks 1. Upon each carriage 5 is mounted a dewatering apparatus 6 of any suitable construction. It may for example consist of a rotary filter, or a launder provided with a filter in the bottom, or a centrifugal separator working either intermittently or continuously as required. 7 represents :a pipe line positioned above the level of the tops and between the two rows of tanks 1, and carried by the trestles 3, for conducting the mill pulp, erushed ore product or mixture of granular or pulverulent solids and liquids, to the dewatering apparatus (i in their several positions above the treatment tanks. 8 are branch pipes, of which one is provided for each tank. for conducting the mixture from the pipe line 7 to the dewatcring apparatus. These branch pipes 8 are fitted with valves or cocks 9 in order to regulate the supply. The dew'atering device 6 is equipped with a discharge chute 10 for conducting the separated solids either direct into the treatment tanks, or as shown on to a rotatable table or plate 11, for distributing the solids inside the. tank. 12 represents a suitable motor, 13 a belt, let a pulley and 15 a shaft for driving the table 11 at a suitable rate of speed. Any other suitable driving means for the distributor may be substituted for those "shown and described. 16 represents'the launder shown located above the level of the tops of the tanks at or about the level of the dewatering device 6, and beneath the pipe line 7, and carried by the trestles 3, for receiving the separatedliquid from the dewatering desolids shall remain on the surface of the position that the scrapers 36 of said convice and for conducting it to any desired point. The dewatering device is equipped with a drainage pipe 17 shown leading to a pump 18 which serves for elevating the separated liquid to the launder 16.

The dewatering apparatus may be constructed either in the manner shown in Fig. 5 or in any other suitable manner. In Fig. 5 it is shown comprising a rectangular box fitted at or about the center of its height with a perforated plate 32 or its equivalent supported by transverse laths 33 carried by longitudinal bars or members 34 of L or any other suitable section. 35 represents a scraper conveyer arranged in the upper portion of the box above plate 32 in such a veyer project to within a suitable short distance of the top of said plate as shown, in order to insure that a quantity of the filtered plate 32 to constitute a portion of the filter bed. The direction of travel of the scraper conveyer 35 is indicated by the arrows 37. The scrapers 36 operate, as will be well understood, to scrape the solids from the receiving to the outlet end of the dewatering apparatus. 38 represents an inclined plate or chute which serves for deflecting the solids to an aperture through which they pass to the inclined chute or launder 10 delivering them on to the rotatable distributing plate or disk 11. The compartment formed beneath the perforated plate 32. as indicated at 39, is preferably constructed with inclined sides leading to the inlet orifice of drainage pipe 17. The action of the pump 18 by establishing a par tial vacuum in the chamber beneath plate 3. draws the filtrate or separated liquid component of the pulp or mixture of solids and liquids through the interstitial spaces I existing between the grains or pfiltlClQ: of the solids and through the perforations in the plate into said compartment.whence it flows through pipe 17 to pump 18 and is delivered by the latter to launder 16. When this apparatus is utilized for separatiifi the sands or coarser particles from crush ore prod- 'ucts, then the water and slimes or minute particles of solids separated from the sands by the dewartering apparatus 6, will be conveyed by the drainage pipe 17 to the pump 18 and lifted by the latter through pipe 18 to the launder 16, which would serve to cona duct them to the slimes plant for further treatment. It will be evident that the launder 16 may be arranged in such a position in relation to the dewatering apparatus that the water and slimes separated thereby from i the sands may gravitate into it either with or without the assistance of a vacuum or of 1 pressure in the apparatus. In the figures the pipe hue 7 and the;

launder 16 serve for supplying the mixture 3 said carriage adapted ceases to, and receiving the separated liquid from, the dewatering apparatus 6 for both rows of tanks 1.

Referring to the modified form of the invention illustrated in Figs. 3 and 4, 19 represent the tanks shown arranged in the form of a circle. In this case the bridge or frame 20 is pivotally supported at one end on a suitable stationary support 21 located at the center of the arrangement of tanks 19 and equipped with wheels at the other end for traversing a circular track 22 supported by trestles 22* rovided round the tanks. This bridge or me 20 carries the dewater' apparatus 23 which may be constructed di id arranged as described in connection with 1 and 2. The frame 20 is also shown carrying a distributer of the construction previously described. The pulp or mixture is conducted by pipe 24 to a hopper 9.5 carried by a frame :26 on the bridge 20 above the stationary support 21 and by pipe 25 from hopper 25 to the dewatering apparatus The pipe 24 is shown supported by the trestles 26* which serve also for carry' an overhead gangway 27. The separa water or liquid conducted from the dewatering apparatus by the drain pipe 28 to the pump 29 is lifted b the latter througltxpipe 30 to the inclined aunder 31 support by the trestles 26 The feed pipe 24% for the dewatering apparatus 23 is preferably provided with a valve 31 or its uivalent actuated from the gangway 27 or regulating the supply to the hopper 25. It is apparent that in any position of the dewatering ap paratus 23 over any one of the treatment tanks 19 the hopper 25 will always remain beneath the outlet of the teed pipe 24, and

1 the pipe 30 always remain over and dis- 1 charge mto the launder 31.
